Blocked sewer? Avoid damaging a gas line

If you need to clear a blocked sewer, be sure to make the free call for safety first. The underground natural gas line may intersect the sewer or septic pipe outside your building. This is called a cross bore – not a safety risk if left undisturbed.
But if the gas line is damaged by motorized or water-jetting equipment used to unclog the sewer, you could have a dangerous gas leak on your hands.

It’s important to know what’s below before anyone – you, your plumber or contractor – goes at it with motorized equipment.
